Shloka – Bhagavad Gita – Chapter 2 – 20

न जायते म्रियते वा कदाचिन्नायं भूत्वा भविता वा न भूयः ।
अजो नित्यः शाश्वतोऽयं पुराणो न हन्यते हन्यमाने शरीरे ॥२- २०॥

This Atma never takes birth, nor dies, nor does it come into existence,

It is unborn, always there, oldest, and even when the body dies, it never dies.
